The story starts in London on Tuesday, October 2, 1872. Fogg is a rich English gentleman living in solitude. Despite his wealth, Fogg lives a modest life with habits carried out with mathematical precision. Very little can be said about his social life other than that he is a member of the Reform Club.

Having dismissed his former valet, James Foster, for bringing him shaving water at 84 °F (29 °C) instead of 86 °F (30 °C), Fogg hires a Frenchman by the name of Jean Passepartout as a replacement.

At the Reform Club, Fogg gets involved in an argument over an article in The Daily Telegraph stating that with the opening of a new railway section in India, it is now possible to travel around the world in 80 days. He accepts a wager for £20,000 from his fellow club members, which he will receive if he makes it around the world in 80 days.

Accompanied by Passepartout, he leaves London by train at 8:45 P.M. on Wednesday, October 2, 1872, and is due back at the Reform Club at the same time 80 days later, Saturday, December 21, 1872.
